Riedel's lobe (ectopic lobe), also known as the accessory hepatic lobe, consists of an anatomical variation characterized by a tongue-shaped protrusion on the visceral surface of the liver right lobe, fixed by a pedicle. This variant draws attention in the clinical practice, as it can be mistaken for a tumor due to its elongated aspect. The aim of this research was to conduct a study on the anatomical characteristics and clinical and functional peculiarities of the accessory hepatic lobe. The paper is based on a integrative review and observational study on a cadaveric specimen. A cadaver with anatomical variation was used. Data were collected in PubMed, Scielo, and VHL. 257 articles were found in the databases, but only 13 were used for research. In careful review, two rare cases of the accessory lobe in the left lobe of the liver, hypoplastic left lobes, and agenesis of the right hepatic lobe, and often the clinical picture without changes in signs and symptoms were found. These morphological abnormalities' clinical impact is limited in the absence of underlying liver disease, cirrhosis, or known cancer. In case of complications or after the diagnosis of pedunculated tumors in the liver, laparoscopy is well indicated for removing these lobes or tumors.

Thyroid hemiagenesis (TH), very rare congenital anomaly, is generally asymptomatic. We report two cases of TH with hyperthyroidism.Case One. The patient presented with signs and symptoms of thyrotoxicosis. Physical examination revealed asymmetric nodular goitre at right lobe. Biochemical analysis revealed the diagnosis of hyperthyroidism. Ultrasound showed multinodular hypertrophy in the right lobe and absence of the left lobe. Nuclear scan, confirming absence of the left lobe, showed hot nodules in the right one. The diagnosis was toxic multinodular goitre.Case Two. The thyroid was not palpable in this patient presented with signs and symptoms of thyrotoxicosis. Biochemical analysis revealed the diagnosis of autoimmune thyrotoxicosis. Ultrasound showed mild diffuse hyperplasia of the right lobe and agenesis of the left lobe. Nuclear scan, confirming absence of the left lobe, showed increasing diffuse uptake of radiotracer in the right one. The diagnosis was Graves’ disease in this patient. After antithyroid medication, the patients were surgically treated with total excision of the thyroid tissue. TH is sometimes associated with disorders of the thyroid. Hyperthyroidism makes TH cases symptomatic. During evaluation of patients, ultrasound and nuclear scan usually report agenesis of one lobe and establish the diagnosis of TH. The surgical treatment is total removal of hyperactive tissue and total excision of the remaining lobe.

AbstractAimTo investigate the radiological characteristics of developmental anomalies of the right hepatic lobe and to systematically compare the efficiency of CT, MR and ultrasound (US) imaging in revealing characteristics of these disorders.MethodsThis retrospective study was approved by the institutional review board, and the requirement for informed consent was waived. CT, MR or US imaging and clinical data of 43 cases with developmental anomalies of the right hepatic lobe were independently reviewed by two experienced radiologists. Systematic comparative analysis of the CT, MR, and US imaging data indicating the main signs of right lobe aplasia or hypoplasia were obtained. Then, c2tests were performed to compare the results, considering P<0.05 as the significance threshold.ResultsAgenesis of the right hepatic lobe was observed in two cases. The main imaging features were agenesis of the right lobe and the absence of the right branch of the portal vein and hepatic artery, although one patient exhibited right diaphragm agenesis and a diaphragmatic hernia. Aplasia or hypoplasia of the right hepatic lobe was observed in 41 patients, and among these patients, the main radiological characteristics were as follows: right lobe volume reduction and stenosis of the right portal vein (41 cases, 100%), ectopic gallbladder (39 cases, 95%), left lobe hypertrophy (39 cases, 95%), left portal vein thickening (37 cases, 90%), dextral displacement of the first hepatic portal (32 cases, 78%), caudate lobe hypertrophy (16 cases, 39%), cholelithiasis (12 cases, 29%), portal hypertension (14 cases, 34%), tumor complications (11 cases, 27%), liver abscess (2 cases, 5%), concurrent intrahepatic bile pneumatosis (5 cases, 12%), dysplasia of the right hepatic bile duct (2 cases, 5%), and Budd-Chiari syndrome (2 cases, 5%). Comparative analysis of the main signs of right lobe hypoplasia revealed no significant difference in overall diagnostic efficiency between CT, MRI and US (CT VS MR, X2= 6.28, P = 0.985; CT VS US, X2= 11.2, P = 0.797; US VS MR, X2= 8.48, P = 0.903).ConclusionThe main radiological characteristics of developmental anomalies of the right hepatic lobe were right lobe volume reduction, stenosis of the right portal vein, ectopic gallbladder, left lobe hypertrophy and dextral displacement of the first hepatic portal. By combining the data from imaging methods (CT, MRI, and US) with clinical data, developmental anomalies of the right hepatic lobe can be relatively accurately diagnosed. The results of this systematic comparative analysis may improve our understanding of this disease.

Background. Thyroid carcinoma complicated by hemiagenesis is very rare, and previous reports have not described this cancer on the side of the absent lobe. Methods and Results. We report the case of a 64-year-old woman in whom left thyroid hemiagenesis was discovered incidentally during investigations of abnormal sensation during swallowing. A tumorous 1.4 cm lesion was also found on the side of the absent lobe, left of the isthmus. Fine-needle aspiration biopsy revealed class V papillary carcinoma, but no lymph node metastases. Total thyroidectomy was performed for stage cT1bN0M0 carcinoma. Histopathology revealed normal thyroid tissues in the right lobe and isthmus, while the left lobe was absent. The mostly papillary carcinoma was adjacent to the truncated thyroid tissue, with a portion histologically consistent with poorly differentiated carcinoma. Conclusions. All previously reported cases of thyroid cancer complicated by hemiagenesis have represented carcinoma occurring within the present lobe. This case is extremely rare.

Abstract Background Cystic echinococcosis (CE)/hydatidosis is an important neglected parasitic zoonotic disease caused by the metacestode of Echinococcus granulosus s.l. The present study was designed to identify the pulmonary CE species/genotypes in isolated human underwent to surgery in our center in Southern Iran. Methods The study population of this study were all patients in Fars province who were admitted to Namazi Hospitals for pulmonary hydatid cyst surgery. Thoracic surgery was performed in the thoracic ward and the cyst/s was removed by open surgery via posterolateral or lateral thoracotomy. DNA was extracted from the germinal layer or the protoscoleces. PCR technique was performed using the cytochrome C oxidase subunit1 (cox1) gene, and the products were sequenced. Results A total of 32 pulmonary hydatid cyst samples were collected from 9 (28%) female and 23 (72%) male aged from 4 to 74 years old. A total of 18(56%) cyst/s were in the left lobe and 14 (44%) cysts in the right lobe. Sequence analysis of the cysts showed that 24 samples (75%) were E. granulosus s.s (G1-G3) genotype and 8 (25%) were E. canadensis (G6/G7) genotype. Conclusion E.granulosus s.s genotype was the most prevalent genotype followed by E. canadensis (G6/G7) genotype. There was no significant statistical correlation between cysts’ size, location, genotype strain, and patients’ age and gender.

Objectives: To determine the effect of serum TSH on thyroid dimensions of each lobe and to measure the amount of effect of per unit increase in serum TSH on thyroid dimensions of each lobe in euthyroids. Study Design: It was a cross-sectional study. Setting: The study was conducted at Ziauddin University Hospital, Clifton, Karachi. Methodology: Healthy participants aged 21 years and above were included through convenient sampling. Serum Thyroid stimulating hormone was evaluated and ultrasound of thyroid gland TG of 192 euthyroid participants was performed. Spearman correlation and regression analysis was applied to evaluate the relationship between TSH and TG dimensions Results: Relationship of increase in serum TSH with decrease in light lobe AP dimension was most significant. (r= -0.142 P-Value=0.001) and CC dimension least significant (r= -0.0098 P-Value=0.001). Where as in the left lobe AP dimension decreases significantly with increase serum TSH (r= -0.147 P-value=0.001). 11.7% of total variation in AP dimension, 3.5% of total variation in ML dimension and 6.5% of total variation in CC dimension in right lobe thyroid are because of serum TSH. While 9.5% of the total variation in AP dimension in left lobe is also due to serum TSH. Conclusion: Negative and significant correlation between serum TSH and thyroid dimensions was observed. Serum TSH inversely and significantly affects all the dimensions of the right lobe and only one dimension in the left lobe

Abstract: Migration of swallowed foreign bodies from the gastrointestinal tract is a rare phenomenon compared with the total number of ingestions. In the reported two cases, the serious septic condition indicated urgent surgical intervention. We found a piece of wire swallowed a few months earlier in the right lobe of the liver and the retroperitoneum in case one, and a piece of wire in the pericardium, which migrated from the stomach through the left lobe of the liver, in case two. Abscesses and phlegmonae were found in the retroperitoneum and then in the femoral region requiring a reoperation in case one, and in the liver and pericardium in case two. After the evacuation of abscesses, both patients made full recovery. Diagnostic difficulties and therapeutic challenges served the reasons to present these cases.

Introduction. Agenesis of the right lobe of the liver is a rare finding and was defined as the absence of liver tissue on the right side, with preservation of the middle hepatic vein, without previous disease or surgery. It is usually an incident finding reveled by imaging exams or during abdominal surgery.Case Report. A 32-year-old male patient was admitted to the hospital for abdominal discomfort and loss of appetite. Imaging studies revealed the absence of the right hepatic lobe and hypertrophied left hepatic segments.Discussion. Anomalies of hepatic morphology are rare and correspond to developmental defects during embryogenesis, are a rare diagnosis, and are generally diagnosed incidentally based on imaging. Agenesis or hypoplasia of the right lobe may predispose the patient to the development of portal hypertension and esophageal varices. Surgical knowledge of such anatomical agenesis is necessary for surgical planning, for the appropriate identification of intraoperative surgical findings, and for the design of the postoperative approach to therapy.Conclusion. Agenesis of the right hepatic lobe is a rare condition. We want to highlight the importance of understanding the condition. Surgeons must recognize the entity in order to deal appropriately with the findings.

Thyroid hemiagenesis is a rare congenital anomaly in which one lobe of thyroid gland fails to develop. It is much rarer in males. There is a higher incidence of associated thyroid disorders in patients with thyroid hemiagenesis; therefore early and prompt diagnosis is important for children. We present the ultrasonographic and scintigraphic findings of thyroid hemiagenesis in an eight-year-old-boy. On ultrasonography (US), left lobe of the thyroid gland could not be demonstrated and the right lobe showed minimal hyperplasia. Its echogenicity was normal and no nodule was seen. On thyroid scintigraphy, left lobe of thyroid gland or any ectopic thyroid tissue could not be demonstrated, while the right lobe showed minimal hyperplasia. Without performing any invasive procedure, we enrolled the child in a follow-up program with the guidance of US and scintigraphy, which were effective both in making the final diagnosis of thyroid hemiagenesis and in evaluating the current status of the present thyroid tissue. In conclusion, if only one thyroid lobe is detected in a pediatric case initially with US or scintigraphy, the diagnosis of thyroid hemiagenesis should be suggested and, before any unnecessary or invasive attempt, the other complementary method (scintigraphy/US) should be performed.

1. In a series of rabbits the changes which took place in the histology of the left lobe of the thyroid gland after excision of the right lobe have been studied at varied intervals of time. 2 days after the removal of one lobe the other lobe showed a slightly increased colloid content, an increased vacuolation of the colloid, and a slight increase in the size of the epithelial cells. At the end of a week the vesicles were greatly increased in size, distended with colloid, and the epithelial cells were flattened, while after 3 to 4 months signs of compensatory hypertrophy were present. 2. The changes observed were uninfluenced by division of the vagus or cervical sympathetic.

Yttrium 90

Background. When associated with isolated four or fewer liver foci, metastatic colorectal cancer is amenable to surgical resection. Alternative therapeutic methods for isolated liver metastases include radioembolization with yttrium 90 (Y90) and transarterial chemoembolization (TACE). We present here a case of a patient with two sites of liver metastatic disease from colorectal cancer who underwent Y90 radioembolization combined with aflibercept and FOLFIRI.Case Report. A 56-year-old female with history of bilateral breast cancer and metastatic colon cancer with prior hemicolectomy and 4 previous chemotherapy regimens developed liver metastasis. She was started on aflibercept and FOLFIRI and concurrently underwent two treatments of radioembolization with Y90, initially targeting the largest right lobe tumor, and then a subsequent treatment targeting the smaller left lobe tumor with retreatment of the right lobe tumor. Her liver metastases exhibited partial response on imaging utilizing the modified RECIST criteria. Interestingly, the patient CEA levels decreased after the procedure.Discussion. This is the first reported case of a patient managed with radioembolization with Y90 combined with aflibercept, an anti-VEGF treatment, and FOLFIRI. An ongoing randomized clinical trial aims to define the role of combined targeted therapy and chemotherapy with radioembolization with Y90.
